Hatter meets her in San Francisco while in pursuit of samurai sword with a Wonderland connection. At first she's just some punk kid who steals his hat, leading him on a merry chase across the city's rooftops. But soon she becomes something more ... the teacher he's needed for years.

But her lessons aren't easy. They challenge him physically. Mentally. Psychically. And they take him to the most perilous location he's ever experienced: The interior of his own mind. It's a challenging journey. But he must undertake it. For only they can he find the answer he's been seeking: The true location of Alyss Heart."
